Waterbeds usually consist of two types, hard-sided beds and soft-sided beds. Early waterbeds were hard-sided consisting of a frame resting on a deck and platform, upon which was the water-containing mattress. Soft-sided waterbeds look very similar to conventional beds and are designed to fit on existing bedroom furniture. First generation waterbeds had only one water chamber, so when disturbed significant wave-action could be felt.
Later generations of waterbeds took on wave-reducing methods, including fiber batting and interconnected water chambers. More modern waterbeds have a mixture of air and water chambers, which are usually interconnected. There are many advantages to owning a waterbed, but of course along with the advantages, come some disadvantages.
